'Lovely girls' comment made McNamara pale

The daughter of murder suspect Glen McNamara has told his Sydney trial that on the day Jamie Gao is said to have been killed, McNamara's alleged accomplice Roger Rogerson said something that made her father blanch.

Jessica McNamara testified on Tuesday that she arrived home from work to an empty apartment around 5.15pm on May 20, 2014, and her father and Rogerson arrived a short time later.

She said the three of them exchanged chit-chat as McNamara and an apparently "jovial" Rogerson shared a beer, but the mood turned when Rogerson commented on how "nice" she and her younger sister were.

"He said to my dad that he had really lovely, lovely girls," Ms McNamara told the NSW Supreme Court.

"As he was saying that I looked at my dad and he was pale.

"He looked skittish. He kept moving at the table, twitching a little bit."

Ms McNamara, 25, said she noticed Rogerson began tapping a dark-coloured item in his right trouser pocket and that her father suddenly began fidgeting, standing up and pacing on the spot.

Prosecutors allege that only hours earlier, Rogerson and McNamara had murdered Mr Gao, a 20-year-old university student and alleged drug dealer, in a storage shed before stripping him of 2.78kg of ice and dumping his body at sea.

Ms McNamara said her father hardly ate a thing that night at dinner.

"He sat there playing with cutlery and not eating. He was just talking," she said.

"He seemed dazed."

McNamara slumped forward in the dock on Tuesday and held his head in his hands, wiping away tears as his eldest daughter described the regular fishing trips they had taken together in the family boat.

The Crown alleges it was this boat that McNamara used to dump Mr Gao's lifeless body into the ocean.

The body was spotted by fishermen on May 26, 2014, wrapped in a surfboard bag and a blue tarpaulin and bobbing in waters off Cronulla.

McNamara's barrister Kara Shead has previously told the jury it was Rogerson who shot and killed Mr Gao, and that while her client admitted being involved in disposing of the body, he did so under duress after Rogerson threatened him and his family.

Rogerson's counsel, meanwhile, says it was McNamara who pulled the trigger.

Ms McNamara is expected to continue giving evidence when the trial resumes on Wednesday before Justice Geoffrey Bellew.
